EMILIO ENRIQUE DUSOHEK, OF BUENOS AYEES, ARGENTINA.

ROTATIVE MOTOR.

To all whom "it may concern:

Be it known that I, EMILIO ENRIQUE DUSOHEK, a subject of the Emperor of Austrialdungary, and resident of Buenos Ayres, Argentina, have invented certain new and useful Improvements in Rotary Engines, of which the following is a specification.

The object of the invention is to provide a simple, and eficient rotary device which may be used as a rotary engine and also as a rotary pump.

An embodiment of the invention is shown in the accompanying drawings, in which,

Figure 1 is a plan view of a portion of the engine. Fig. 2 is an end elevation. Fig. 3 is a longitudinal section on line AB' of Fig. 1. Fig. 4 is a transverse section on line C-D of Fig. 1. Figs. 5 and 6 are detailed views of the valve operating means. Figs. 7 and 8 are detailed views.

Referring by reference characters to this drawing, the numeral 1 designates an inlet for the motor fluid, such as steam, which is controlled by a valve 2. Then this valve is opened, as hereinafter described, the steam passes into. the space 3 which is divided off from the annular steam chamber 7 by a sliding abutment 9 and the rotary piston 4. The annular steam chamber 7 is formed be tween the parallel side walls and the inner and outer curved walls, as shown in Figs. 3 and 4 and the steam being allowed to 6X- pand between the stationary abutment 3 and the rotary piston 4 causes the latter to rotate and thus impart movement to the shaft 6. As the piston 4 rotates, it passes the outlet of the pipe 8 which allows the steam to exhaust, the valve 2 in the meantime being closed to cut off the inlet of steam. As the piston 4 continues to rotate, it would Specification of Letters Patent.

of course strike against the sliding abutment 9 and the latter is accordingly retracted to allow the piston 4 to pass. This is accomplished by having projecting rollers as shown'in Figs. 7 and 8, which extend into eccentric grooves in the rotating wheels 10 shown therein.

The inlet valve is operated by a cam 11 carried by the shaft which engages a strap connected by the rod 12, which in turn is connected to the rocking lever 13. The action of this rocking lever opens the valve 2 at the proper time against the tension of a spring 14.

Having thus described my invention, what I claim is v A rotary engine comprising a cylinder, a rotary shaft passing through said cylinder, a sliding abutment in said cylinder, a rotary piston within the cylinder and connected withthe shaft, wheels on each side of the cylinderand .mounted on the shaft, said wheels having cam grooves therein, projections on the abutment fitting in said grooves so as to open the abutment to permit the passage of the piston, a steam inlet leading to the cylinder, a spring pressed valve inclosing said inlet, a two armed lever having one end engaging the said valve, a cam on the shaft and a lever connected with the other arm of the two armed lever and operated by said cam to open said valve at the proper time. i

In witness whereof,I have hereunto signed my name in the presence of two subscribing witnesses.

EMILIO ENRIQUE DUSCHEK.
